Time: From Earth Rotation to Atomic Physics


Book Description

This accessible reference presents the evolution of concepts of time and methods of time keeping, for historians, scientists, engineers, and educators.

Time, Globalization and Human Experience


Book Description

This edited volume focuses on the intersection of time and globalization, as manifested across a variety of economic, political, cultural, and environmental contexts. Since David Harvey’s influential characterization of globalization as "time-space compression", ample research has looked at the spatial aspect of the phenomenon, yet few have focused on globalization’s temporal aspects. Meanwhile, other publications have analysed problems of speed, acceleration, and the commodification of time, but while it often serves as the implicit or explicit backdrop for these studies of time, globalization is not investigated as a problem or a question in its own right. In response, this volume develops these conversations to consider how time shapes globalization, and how globalization affects our experience of time. The interplay between varying aspects of the human experiences of time and globalization requires the type of interdisciplinary approach that this volume takes. The contributors advance an understanding of global time(s) as an arena of contestation, with social, political, ecological, and cultural implications for human and other lives. In considering the diverse valences of time and globalization, they illuminate problems as well as possibilities. Topics covered include emerging infectious diseases, temporal sovereignty, worker exploitation and resistance, chronobiology, energy politics, activism and hope, and literary and cinematic representations of counter-temporalities, offering a rich and varied account of global times. This volume will be of great interest to students and researchers from a range of disciplines, including anthropology, cultural studies, globalization, international relations, literary studies, political science, social theory, and sociology.




Ethnographies of U.S. Empire


Book Description

How do we live in and with empire? The contributors to Ethnographies of U.S. Empire pursue this question by examining empire as an unequally shared present. Here empire stands as an entrenched, if often invisible, part of everyday life central to making and remaking a world in which it is too often presented as an aberration rather than as a structuring condition. This volume presents scholarship from across U.S. imperial formations: settler colonialism, overseas territories, communities impacted by U.S. military action or political intervention, Cold War alliances and fissures, and, most recently, new forms of U.S. empire after 9/11. From the Mohawk Nation, Korea, and the Philippines to Iraq and the hills of New Jersey, the contributors show how a methodological and theoretical commitment to ethnography sharpens all of our understandings of the novel and timeworn ways people live, thrive, and resist in the imperial present.

Proceedings of the Twenty Seventh General Assembly Rio de Janeiro 2009


Book Description

A complete record of the formal organisational and administrative proceedings of the XXVII General Assembly of the International Astronomical Union.




Encyclopedia of the Solar System


Book Description

Long before Galileo published his discoveries about Jupiter, lunar craters, and the Milky Way in the Starry Messenger in 1610, people were fascinated with the planets and stars around them. That interest continues today, and scientists are making new discoveries at an astounding rate. Ancient lake beds on Mars, robotic spacecraft missions, and new definitions of planets now dominate the news. How can you take it all in? Start with the new Encyclopedia of the Solar System, Second Edition.This self-contained reference follows the trail blazed by the bestselling first edition. It provides a framework for understanding the origin and evolution of the solar system, historical discoveries, and details about planetary bodies and how they interact—and has jumped light years ahead in terms of new information and visual impact. Offering more than 50% new material, the Encyclopedia includes the latest explorations and observations, hundreds of new color digital images and illustrations, and more than 1,000 pages. It stands alone as the definitive work in this field, and will serve as a modern messenger of scientific discovery and provide a look into the future of our solar system.· Forty-seven chapters from 75+ eminent authors review fundamental topics as well as new models, theories, and discussions· Each entry is detailed and scientifically rigorous, yet accessible to undergraduate students and amateur astronomers· More than 700 full-color digital images and diagrams from current space missions and observatories amplify the chapters· Thematic chapters provide up-to-date coverage, including a discussion on the new International Astronomical Union (IAU) vote on the definition of a planet· Information is easily accessible with numerous cross-references and a full glossary and index







New Approaches In Geomagnetism And The Earth's Rotation


Book Description

The rotation of the Earth and its relation to geomagnetism are topics that have been under debate for more than a century. In this volume both of these phenomena are discussed in the light of new approaches. Keith Runcorn presents a survey of the papers and concluding remarks. F Richard Stephenson gives a thorough review of the history of the Earth's rotation whilst Stig Flodmark finds an explanation for the Chandler wobbles and the drift of the polar axis. A New Approach to Polar Motion by Losito et al. gives another view of the same theory. The fascinating idea of a single-crystal inner core is discussed by Flodmark and Weber and magnetic rigidity in the Earth is a new concept dealt with by Mörner. The mechanisms behind magnetic reversals, ice ages and earthquakes are other subjects under debate. It is hoped that the present volume will encourage forthcoming debates on these subjects.







Historical Eclipses and Earth's Rotation


Book Description

This book is intended for geophysicists, astronomers (especially those with an interest in history), historians and orientalists. The culmination of many years of research, it discusses, in depth, ancient and medieval eclipse observations and their importance in studying Earth's past rotation. This was the first major book on this subject to appear in the last twenty years. The author has specialised in the interpretation of early astronomical records and their application to problems in modern astronomy for many years. The book contains an in-depth discussion of numerous eclipse records from Babylon, China, Europe and the Arab lands. Translations of almost every record studied are given. It is shown that although tides play a dominant long-term role in producing variations in Earth's rate of rotation - causing a gradual increase in the length of the day - there are significant, and variable non-tidal changes in opposition to the main trend.
